IntroductionThis paper is a continuation of the ongoing taxonomic revision of nine Neotropical

genera of the subtribe Odontocheilina W. Horn, 1899 by the first author. The aim of thisseries of papers (see MORAVEC 2012a,b,c, and 2013, DURAN & MORAVEC 2013, MORAVEC& BRZOSKA 2013 and MORAVEC & DURAN 2013) is to publish significant taxonomic andnomenclatorial changes or descriptions of new taxa to be available before the completionof the final comprehensive publication.

The subtribe Odontocheilina W. Horn, as discussed by MORAVEC (2012a), is heredefined exclusively for the Neotropical genera, and in the present sense is separated fromthe subtribe Prothymina W. Horn, 1910 sensu RIVALIER (1969, 1971). The subtribe name,originally spelled by HORN (1899) as Odontochilina, is emended as Odontocheilinaaccording to Art. 35.4.1 (ICZN 1999).

Contrary to the classification character of glabrous thoracic and abdominal sternaused by RIVALIER (1969, 1971) to support his broad concept of the subtribe Prothymina,many species of the Neotropical Odontocheilina placed within Prothymina by Rivalierhave setose sterna. The presence of such setal vesture, particularly developed in the genusPentacomia Bates, 1872 and most distinctly in the genus Brzoskaicheila Moravec, 2012

where the setae may even cover dorsal body surfaces (MORAVEC 2012b), was entirelyignored by Rivalier. In fact, the chaetotaxy is important not only for the classification ofthe subtribe, but also represents one of the most important diagnostic characters foridentification of species.

Bolivia is one of the world�s megadiversity centres (MITTERMEIER & MITTERRMEIER1997). The Bolivian tiger beetle fauna has been recently explored by several specialistsin Cicindelidae. A large number of specimens have been collected by David L. Pearsonof the Arizona State University and others including the second author as a part of asurvey conducted by the Museo de Historia Natural, Santa Cruz. A possibility ofundescribed species was mentioned by GUERRA, BRZOSKA & PEARSON (1997), and thetremendous biodiversity in Bolivia has been confirmed and from the rich materialobtained from these surveys five new species of the subtribe Odontocheilina (in the senseunderstood here) were described by HUBER (1999). An overview of 102 species of thefamily Cicindelidae in Bolivia was published by PEARSON, GUERRA & BRZOSKA (1999).It included simple keys, notes to identification and biology, distribution maps and fullysited localities. These authors stated that Bolivia has the largest number of tiger beetlespecies among the five north-Andean countries of South America, including 18 speciesof the genus Pentacomia .

The genus Pentacomia, subdivided by RIVALIER (1969) into four subgenera,presently comprises approximately 40 taxa that will be entirely reviewed in the finalrevision of the subtribe by the first author, with a new infrageneric classification and keysto subgenera and species. ERWIN & PEARSON (2008) treated 42 taxa (includingsubspecies). Recently, one new species was described from Panama (DURAN & MORAVEC2013) and one from Costa Rica (MORAVEC & BRZOSKA 2013).

Regarding the Bolivian species, P. (Mesacanthina) ronhuberi Moravec, 2012 wasrecently described (MORAVEC 2012c). This species, together with the closely related P.(Mesacanthina) punctum (Klug, 1834), occur in Bolivia and Brazil, and were listed fromBolivia by PEARSON, GUERRA & BRZOSKA (1999) under the name P. (M.) punctum.

The new species described here, P. (Pentacomia) davidpearsoni sp.nov., was foundamong specimens of a similar, related species P. (Pentacomia) speculifera (Brullé, 1837),and was listed by PEARSON, GUERRA & BRZOSKA (1999) under the latter name. While P.(P.) speculifera occurs both in Bolivia and Brazil, the new species is known only fromthree localities in Bolivia.

Material and methodsBody length is measured without the labrum and is the distance from the anterior

margin of the clypeus to the elytral apex (including the sutural spine). The width of thepronotum includes the lateral margins of the proepisterna (when the proepisterna and thenotopleural sutures are visible from above). The width of the head is measured across theeyes, the distance between their outer margins. The term �aedeagus� here refers to themedian lobe of the organ (without parameres). All dimensions of aedeagi are measured(and primarily figured) in their left lateral position where the basal portion (with basalorifice) points to the right and the left lateral outline (with dorsoapical orifice) faces

dorsally, provided that the ventral outline of the median portion is settled in its verticalposition, and both upper and lower walls of the dorsoapical orifice are in the same line.The treatment and mounting of the aedeagi, in order to observe the structure of theinternal sac, followed the usual procedure as modified and the terms explained inMORAVEC (2002, 2010). The colour photographs of the habitus and diagnostic characters,including aedeagi, were taken with a Nikon Coolpix 990 digital camera through an MBS-10 binocular stereo microscope by the first author.

Labels are cited in the following manner: lines on the same label are separated byslash /, separate labels are indicated by double-slash //. The colour of the label and modeof writing appear in square brackets (in type specimens only).

The list (catalogue) under the species name in the descriptive part is selective. Itmeans that it gives the original name combination, as well as the first publication of allsubsequent taxonomic or nomenclatorial acts concerning the taxon.

Following abbreviations of type status are used in the descriptions and captionsbelow the illustrations: HT = holotype; PT = paratype, AT = allotype; LT = lectotype.

Pronotum (Figs 11�12) only slightly longer than wide, length 1.40�2.20mm, width 1.30�1.90 mm, sulci well pronounced; anterior lobe only slightly wider thanthe posterior but much higher, irregularly, finely rugulose, rugae mostly vermicular totransverse wavy, coarser on sublateral areas; disc mostly with distinctly convex lateralmargins (including clearly visible proepisterna) giving the disc a subglobose shape,notopleural sutures thin but clearly obvious in dorsal view; median line mostly thin butwell pronounced on whole discal length; discal surface finely rugulose, rugae onsublateral areas more irregular and wavy but mostly continuous, towards the middlebecoming more stria-like, parallel and continuous, converging towards the median line;juxtanotopleural area with sparser and coarser transverse rugae; posterior lobe irregularlyand rather finely irregularly rugulose, rugae mostly vermicular in middle, much coarseron lateral areas and irregularly transverse adjacent to distinct posterior rim; proepisternasmooth and shiny, glabrous except for a few setae adjacent to their ventral suture;mesepisterna smooth and glabrous, shiny black with faint golden-bronze, rarely greenlustre; metepisterna of the same coloration, but with two deep impressions with a fewsetae at metepimeron; female mesepisternal coupling sulci indistinct as lacking any pit,in form of a longitudinal furrow which is only somewhat deeper than in male; ventralthoracic sterna concolorous with the lateral sterna; prosternum and mesosternum almost


20


smooth and glabrous; metasternum distinctly punctate-setose with white, rather shortsetae which are densest on lateral areas, sparser on anterior area and absent on smoothand shiny posteromedian area.

Elytra (Figs 13�15) elongate, length 4.10�6.10 mm, with rounded humeri, lateralmargins almost straight in male, in female slightly dilated in middle, in both sexes withslightly convex subhumeral area, anteapical angles arcuate, then obliquely runningtowards apices which are in female variably arcuate or rounded, in male more subacute;sutural spine short but distinct, variably acute or blunt; microserrulation fine but usuallydistinct; elytral dorsal surface markedly uneven due to several impressions: humeralimpressions deep, continuously connected with large and deep discal impression, thusdelimiting distinct basodiscal convexity and another distinctly raised discal convexityformed by deep impression of the area of large median catoptric patch; apical andsublateral-anteapical impression distinct, and additional, subsutural-anteapicalimpression present on raised juxtasutural area; whole elytral surface notably coarselypunctate, punctures mostly isodiametric, large and deep with narrow and sharp intervals,largest on anterior elytral half, mostly isolated, but largest punctures particularly onelytral base near humeri are occasionally irregularly connected; smaller but densepunctures on juxtasutural-discal area anastomosing in short chains; punctures onposterior elytral half become only indistinctly smaller than those on anterior half, thoseon anteapical area are somewhat longitudinally prolonged; apical area possess veryirregular sculpture; punctures are effaced only within two shiny catoptric patches whichappear shiny black but change to shiny silvery depending on the angle of illumination:the patch on the basodiscal convexity appears usually smaller because its irregularlyjagged margins merge with surrounding large punctures, the catoptric patch placed in themiddle of the elytral disc is much larger, irregularly rectangular, widest in middle andusually with narrower, short, oblique-transverse protrusion towards outer elytral lateralmargin; rarely these two patches are connected by indistinct, longitudinal, narrow smootharea; elytral surface glabrous except for usual, a few and often very indistinct hairlikesensory setae scattered mostly on anterior area, few of them at epipleura and severalothers scattered along the margin of the elytral apex; elytral maculation whitish,consisting in both sexes of three rather distinct maculae: humeral lunule of which only itsposterior part is visible from above, sometimes appearing as a rounded subhumeral spot;lateral-median band which is bent upwards, rarely interrupted into lateral and discalmacula; anteapical macula which is elongate and rather wide.

Legs. Procoxae and mesocoxae brownish-testaceous to brown, often with greenishlustre, densely whitish setose; metacoxae metallic black-blue with greenish lustre,densely punctate-setose on lateral areas and with a few setae also on central area;trochanters smooth, pro- and mesotrochanters tawny to dark-testaceous, metatrochantersdark brown; femora tawny brown to brownish except for limited metallic-black apicalarea, sometimes with faint metallic-green lustre, femoral surface covered with denseirregular rows of mediocre-long and longer, erect and semierect white hairlike setae;tibiae dark brown-testaceous, sometimes with mahogany lustre, apical quarter or halfmetallic-black darkened, covered with scattered, much stiffer, semierect, whitish setae;apical-ventral area of protibiae and mesotibiae covered with dense whitish to greyish


21


setose pad; tarsi metallic black with greenish lustre, rarely dark testaceous with blackapices; first three protarsomeres in male only indistinctly dilated, with dense greyish-white pad of short setae; claws metallic black-green.

Abdomen. Ventrites dark metallic black-blue sometimes with greenish lustre, apicalpleurite usually brownish; surface of last three ventrites smooth and glabrous, but theirposterior margins fringed with dense hairlike setae and the first two visible ventrites withseveral short and rather long hairlike setae present also on their surface.

Aedeagus (Figs 16�18) elongate, length 2.10�2.60 mm, width 0.35�0.40 mm, withshortly arcuate base and narrow, straight whole basal half, while ventrally directed apicalhalf is dilated and then conically attenuated towards elongate, rounded apex which issometimes slightly curved; internal sac (Figs 19�20) well developed, containingconspicuous, medioventral spur with thin, markedly long projection which is wellobservable in left lateral view (Fig. 19), basal bent piece, and two, long dorsal spikestightly alongside each other, therefore better recognisable in the right lateral view (Fig20) because in the left lateral view they appear as confluent together.Variability. The body coloration varies only insignificantly; the smooth catoptric elytralpatches may vary in their size, particularly the basodiscal patch which is also morevariable in the shape of its irregular margins which often merge with the deepsurrounding punctures, while the discal patch is always large. The elytral punctures mayappear more variable because their real shape, particularly of the punctures on posteriorelytral half, appears distorted in front illumination. The aedeagus is somewhat variable inits apex which can be more prolongedDifferential diagnosis. As in most other species of the nominotypical subgenus withnotably uneven elytral surface, the whitish elytral maculation of P. (Pentacomia)speculifera consists in both sexes of humeral lunule, lateral-discal band which is bentupwards (rarely divided into lateral and discal macula), and anteapical macula, but thisspecies is immediately distinguishable by the presence of the large, irregularlyrectangular, smooth catoptric patch placed in the middle of the elytral disc, and a similar,smaller catoptric patch on the basodiscal convexity. These much larger smooth andpolished elytral patches, narrower humeral macula only partly visible from above, thesubglobose-shaped pronotal disc with much finer surface sculpture of predominantlyparallel-arranged stria-like rugae (particularly in middle), darker penultimate palpomeresof maxillary palpi, much darker antennae with metallic-green tinge on the scape whichpossesses only apical seta, and markedly longer median lobe of the labrum in both sexes,immediately distinguish P. (P.) speculifera from P. (Pentacomia) davidpearsoni sp.nov.described below.

In contrast to these constant and reliable external differences, these two speciespossess rather similar aedeagi with apical portion attenuated into rather narrow, roundedapex; the structure of the internal sac in examined aedeagi somewhat differs, but theshape of the sclerites may change depending on their positioning within the internal sac.

P. (Pentacomia) degandei (Tatum, 1851) spelled in the original description (TATUM1851) as Odontocheila De Gandii, later emended as Degandei by FLEUTIAUX (1892: 124)possesses similar whitish elytral maculation and smooth, shiny areas on its elytral


22


surface, but these catoptric areas are of an irregular shape and this species is immediatelydistinguishable from these two species by its uniquely shiny red-cupreous body, usuallywith metallic-green lateral areas, its pronotal disc is covered with much more distinct,continuous arcuate-parallel stria-like rugae conspicuously converging towards themedian line, and its aedeagus is straighter.Biology and distribution. P. (P.) speculifera is known only from Bolivia and Brazil. Itwas considered a very rare species as only the lectotype and a few old historicalspecimens have been deposited in the MNHN, NMPC and SDEI collections and evenentirely missing in other European museum collections. Nevertheless, recent explorationof Bolivia has revealed that this species is rather common in south-eastern Bolivia. Thetype locality Santa Ana de Chiquitos (spelled by BRULLÉ 1837 as �Anna�) in the provinceof Chiquitos of the large Bolivian department of Santa Cruz lies in the southern-easternmost part of Bolivia about 150 km west from Puerto Suarez near the border townCorumbá in the Brazilian province of Mato Grosso. According to the protologue byBRULLÉ (1837) the species was found during October on opened and humid places.

Besides the type locality this species was recently discovered (PEARSON, GUERRA &BRZOSKA 1999) in two localities in the same Bolivian department of Santa Cruz. Thelocality Ñuflo de Chavez (16°20′S, 62°27′W, 470 m), 14 km east of San Javier lies about600 km northwest from the type locality and San Ramon is situated only 50 km southfrom San Javier. The adults occupied forest trails with clay banks in a partial shade.

Most historical specimens in collections come from Brazil, mostly from the Brazilstate Goiás (formerly Goyaz) and the area of Cuyaba (=Cuiabá) in the state of MatoGrosso (= Matto Grosso). Chapada (now probably the Chapada dos Veaderios NationalPark) also lies in this large central state of Brazil. Lago Santa (= Lagoa Santa) is the lakein the Brazil state of Minas Gerais (see also HORN 1922). Regarding the specimen(MNHN) labelled Barro Preto it probably refers to Barro Prêto in the Brazilian state ofParana, but there are several homonymous names in Brazil. Remarks. BRULLÉ (1837) in his original description of this species (as Cicindelaspeculifera) mentioned only female sex, probably only a holotype, but as he did notexplicitly mention a number of specimens, the lectotype is designated here for the betterstability of the taxon. As Brullé and other old authors mostly did not originally providetheir type specimens by a label �type�, the female in MNHN, although it bears no originaltype label, is considered to be a syntype and is designated here as the lectotype.Notwithstanding, it represents evidently a type specimen and the only one in all relevantcollections, labelled �Chiquitos / d�Orbigny 1834�, thus corresponding with the typelocality in the original description by Brullé, and collected by Alcide d�Orbigny duringthe �Voyage dans l�Amerique Méridionale�.

It is very interesting that HORN (1899) treated this species as Pentacomiaspeculifera, but later (HORN 1915) as Cicindela (Pentacomia) speculifera, and more laterHORN (1938) surprisingly as Cicindela speculifera. SCHILDER (1953) accommodatedPentacomia speculifera in the genus Phyllodroma Lacordaire, 1842 as he treatedPentacomia as a subgenus of Phyllodroma. His classification was not accepted byRIVALIER (1969) and by any recent authors as the internal sac in Phyllodroma, in contrast


23


to the genus Pentacomia, contains a long, multicoiled flagellum associated with acompact sustaining membrane, thus also differing from the long, coiled, but not sosupported flagellum in the genus Odontocheila. For that reason, and also for some of itsexternal characters, the genus Phyllodroma has an outstanding position within thesubtribe Odontocheilina.

Description. Body (Figs 3�4) small, of rather variable size, 7.45�8.50 (HT 7.50) mmlong, 2.30�2.80 (HT 2.45) mm wide, dorsal surface of head, pronotum and elytra almostuniformly cupreous to rather lustrously bronze-cupreous; elytra with complete whitishmaculation and narrow, obliquely transverse catoptric median band, while the smoothcatoptric patch on basodiscal convexity is only indistinct, irregular or absent.Metasternum punctate-setose on lateral areas.

Head (Fig. 33�34) large, almost as wide as body, or slightly narrower (particularlyin female), 2.30�2.60 mm wide, notably wider than pronotum; all head portions glabrous.

Frons only indistinctly convex in middle, rather steeply sloped towards clypeus andclearly separated from it, lateral areas rather distinctly longitudinally parallel-striate,median area with coarse, irregular, vermicular rugae; supraantennal plates irregularlytriangular, smooth, but their inner margins usually merging with coarse sculpture onlateral areas of frons, shiny cupreous often with green lustre, their apex connected withindistinct or acute but short lateral edge.

Vertex almost flat, rarely with only indicated anterior impressions, anteromedianarea irregularly vermicular-rugulose (the sculpture passing from blunt frons-vertex fold),surface sculpture similar to that in P. (Pentacomia) speculifera but more irregular,usually very irregularly vermicular-rugulose on almost whole vertexal surface, rugae inmiddle only rarely more longitudinal but still irregularly wavy, rugae on posteromedianarea sometimes shortly longitudinal, wavy and indistinctly diverging posteriad;juxtaorbital areas anteriorly irregularly rugulose, longitudinally parallel-striate only ontheir limited posterior area, sublateral areas mostly with vermicular sculpture, onlyindistinctly recognizable as parallel-arranged wavy stria-like rugae running towardstemples; rugae on posteromedian area longitudinal-parallel diverging posteriad onto


24


occipital area which is moderately convex, irregularly rugulose with rugae moretransverse on lateral areas.

Genae metallic-cupreous with golden-bronze lustre on median smooth area, usuallystrong green lustre on anterior and posterior areas, anterior and ventral areas finelywrinkled to striate, juxtaorbital and postgenal area more distinctly striate.

Clypeus predominantly metallic copper with brighter cupreous and faint green lustreon lateral areas, irregularly wrinkled.

Labrum 4-setose, sexually dimorphic in shape, in both sexes shorter than in P.(Pentacomia) speculifera, and mostly ivory to light ochre-yellow; male labrum (Figs28�30) 0.60�0.75 mm long, 1.05�1.15 mm wide, basolateral margins mostly short andstraight with right-angled or blunt basolateral teeth, then lateral margins arcuate formingwide, rounded anterolateral teeth; median tridentate lobe short, either in the same level asthe anterolateral teeth or only slightly surpassing them, consisting of small, mostly right-angled subacute median tooth between much wider but usually mucronate teeth in thesame level; female labrum (Figs 31�32) longer, length 1.00�1.15 mm, width 1.15�1.30mm, of a similar shape except for the median lobe consisting of three large anterior teethresembling a part of a hexagram as the median tooth is only moderately longer (much lessprominent than in P. (Pentacomia) speculifera).

Mandibles (Figs 33�34) normally shaped with arcuate lateral margins, in both sexesnearly symmetrical, each mandible with four teeth (and basal molar), the three inner teethbecoming gradually smaller towards the basal molar; coloration ivory to ochre on widelateral areas, inner area and teeth mahogany-brown, apices of teeth often black-brown.

Palpi (Figs 33�34) normally shaped with elongate terminal palpomeres,conspicuously light, both maxillary and labial palpi ivory-white to ochre-yellowincluding terminal palpomeres except for their brown-darkened apical patch; penultimate(longest) palpomere of labial palpi elongate with almost parallel lateral margins, onlyslightly dilated towards 0.14�0.18 mm wide apex.

Antennae rather short, in male reaching or slightly surpassing elytral third, in femalemuch shorter, reaching or only slightly surpassing elytral quarter; scape (Fig. 35) paleivory to light ochre-yellow, with apical seta and additional l�4 setae placed on the discalarea of the scape (setae easily abraded); antennomeres 2�5 and sometimes alsoantennomeres 6-8 pale ochre-yellow to ochraceous, last three antennomeres smokydarkened.

Thorax. Pronotum (Figs 36�39) slightly to more distinctly longer than wide, length1.55�1.90 mm, width 1.30�1.65 mm, sulci well pronounced; anterior lobe only veryslightly wider than the posterior but notably higher, irregularly coarsely vermicular-rugulose; disc with subparallel to moderately convex lateral margins (including clearlyvisible proepisterna) usually but not always more distinctly convex in females;notopleural sutures clearly obvious in dorsal view, subparallel; median line mostly thinbut developed on whole discal length; discal surface coarsely vermicular-rugulose, rugaeirregularly �zigzag� arranged, partly and indistinctly converging towards the median line;juxtanotopleural area with sparser transverse rugae; posterior lobe covered with the samevermicular coarse sculpture as the disc, but also with irregularly transverse rugae adjacent


25


to posterior rim; proepisterna smooth and shiny, glabrous except for one or three setaeadjacent to their ventral suture; mesepisterna smooth and glabrous, shiny black with faintgolden-bronze and green lustre; similarly coloured metepisterna possess two deepimpressions at metepimeron with a few setae; female mesepisternal coupling sulciindistinct as lacking any pit, with only longitudinal furrow almost unrecognizable from asimilar furrow in male; ventral thoracic sterna concolorous with the lateral sterna, or withbluish lustre; prosternum and mesosternum almost smooth and glabrous; metasternumwith distinctly punctate-setose lateral areas with rather short setae, remaining areasglabrous.

Elytra (Figs 40�42) elongate, length 4.30�5.50 mm, with rounded humeri, lateralmargins in both sexes with slightly convex subhumeral and median areas, anteapicalangles arcuate, then obliquely running towards apices which are variably rounded in bothsexes; sutural spine short; microserrulation indistinct and very irregular; elytral dorsalsurface markedly uneven due to several impressions: humeral impressions deep,continuously connected with large and deep discal impression, thus delimiting distinctbasodiscal convexity which is, however, impressed in juxtasutural narrow area, andanother distinctly raised discal convexity delimited by deep impression on the area of thenarrow, obliquely transverse median catoptric band; apical and sublateral-anteapicalimpression distinct, and additional, subsutural-anteapical impression present on raisedposterior juxtasutural area; whole elytral surface rather coarsely punctate, but puncturesgenerally finer than on the elytra of P. (P.) speculifera, particularly along sutures and onposterior elytral area, mostly isodiametric with narrow and sharp intervals, largest onanterior elytral half, mostly isolated, but the largest punctures particularly on elytral basenear humeri occasionally irregularly connected; smaller but dense punctures onjuxtasutural-discal area anastomosing in short chains; punctures on posterior area ofelytral disc smaller and denser, those on anteapical area more irregular, and veryirregular, deep but dense on apical area giving the area rasp sculpture; the punctures areeffaced only within two shiny catoptric patches which appear shiny black but change toshiny silvery depending on the angle of illumination: the patch on the basodiscalconvexity is usually small, or almost entirely missing, its irregularly jagged marginsmerge with large surrounding punctures, while the patch placed in the middle of theelytral disc is in form of elongate transverse catoptric band, slightly wider in middle (asin the holotype), in some adults very narrow; these two smooth patches are sometimesconnected by another but very indistinct, narrow, longitudinally running smooth area ofwidened intervals; elytral surface glabrous except for usual, a few and often veryindistinct hairlike sensory setae scattered mostly on anterior area, few of them atepipleura and several others scattered along the margin of the elytral apices; elytralmaculation whitish, consisting in both sexes of three rather large maculae: wide humeralmacula clearly visible from above as entire continuous lunule, lateral-median band whichis continuous and bent upwards on the elytral disc, and anteapical macula which iselongate but rather wide.

Legs. Procoxae and mesocoxae ochraceous only rarely with greenish lustre, denselywhitish-setose; metacoxae black-brown to metallic black-blue with greenish lustre,


26


densely finely punctate-setose on lateral areas and with one or two setae on central area;trochanters smooth, ivory to ochraceous; femora ochre-yellow or ochre-brownish withblack apices, femoral surface covered with dense irregular rows of mediocre-long, erectand semierect white hairlike setae; tibiae concolorous with femora, their apices black-darkened, covered with scattered, much stiffer, semierect, whitish setae; apical-ventralarea of protibiae and mesotibiae covered with dense whitish to greyish setose pad; tarsipale ochre with black apices; first three protarsomeres in male only indistinctly dilated,with usual dense greyish-white pad of short setae; claws black-brown.

Abdomen. Ventrites dark metallic black-blue or with greenish lustre, last ventriteusually ochre-testaceous, apical bilobed pleurite in male pale ochre; surface of the visibleventrites smooth and glabrous, their posterior margins with usual, sparse hairlike sensorysetae.

Aedeagus (Figs 21�23) elongate, of a similar shape as in P. (Pentacomia)speculifera, length 2.35�2.60 mm, width 0.40�0.42 mm, with shortly arcuate base thenwith narrow, straight basal half and ventrally directed apical half which is dilated andthen conically attenuated towards rounded apex; internal sac (Figs 24�27) welldeveloped, containing conspicuous, medioventral spur with thin, long filiform projection,basal bent pieces, and two long dorsal spikes appearing as confluent because tightlyalongside each other, sometimes better recognisable in the right lateral view (Fig. 27).Variability. This new species is only slightly variable in body size and coloration whichis in some adults brighter; sometimes the smooth, catoptric, obliquely transverse-elongateand narrow median patch is somewhat wider (as in the holotype), but never so large andangular as in P. (Pentacomia) speculifera. The number of discal setae on the antennalscape varies from one to four, but the setae can be easily abraded.

Regarding the variability of internal sac of aedeagi, the shape of the scleritesdepends both on their positioning within the internal sac, as well as on the position of theinternal sac within the aedeagus �the sclerites can be variously swung, and the wholeinternal sac inside the aedeagus can be variously turned, and consequently, even smalldifferences in the positioning may change the appearance of the structure.

The line drawing of the aedeagus for P. (P.) speculifera by RIVALIER (1969, fig.23sp) is rather schematic and its shape is somewhat deformed (dilated) by the treatmentused by Rivalier in order to observe the internal sac and by mounting the aedeagi betweenglass slides � for that matter most of the aedeagi mounted by Rivalier, unfortunately alsothose of most type specimens, were mostly flattened, by such mounting treatment,damaged or even destroyed by extraction of the internal sacs from the aedeagi (seeMORAVEC 2010). It should be noted that even proper and careful clearing procedures ofthe aedeagi always change their outline shape; they usually become wider and straighter. Differential diagnosis. P. (Pentacomia) davidpearsoni sp.nov. differs from the relatedand rather similar P. (Pentacomia) speculifera in having its dorsal body surface muchlighter coloured, bronze-cupreous to bright-cupreous, and significantly differs infollowing diagnostic characters: conspicuously narrower catoptric patch on the elytraldisc and smaller or sometimes nearly absent basal catoptric spot; wider humeral maculain both sexes clearly obvious from above as a continuous lunule, generally narrower


27


pronotal disc with much coarser and notably irregular surface sculpture consisting ofshort zigzag arranged vermicular rugae; much shorter median lobe of the labrum in bothsexes; ivory to ochre coloured mandibles with only brown teeth; paler penultimate andterminal palpomeres both of maxillary and labial palpi; much paler antennae includingthe ivory to ochre coloured scape which besides the usual apical seta possesses additional1�4 discal setae (these are constantly absent on the much darker, metallic-tinged scape ofP. (P.) speculifera with only apical seta); all leg segments paler, particularly the ochre-testaceous tarsi, and the metasternum punctate-setose only on lateral areas, andabdominal ventrites have setae only on their posterior margins while their surface isglabrous.

Most of these characters and also a rather different shape of the aedeagusimmediately distinguish this new species also from P. (Pentacomia) degandei (Tatum,1851) which is, moreover, unique in the genus due to its conspicuously bright red bodycoloration and its elytra lacking humeral lunule (only a submarginal macula placedposteriad of the humerus present).

Another related species, Pentacomia (Pentacomia) sericina (Klug, 1834) occurs inBrazil. The holotype (MFNB) and five additional specimens (SDEI) have been examinedand compared by the first author. It resembles both P. (P.) speculifera (by its dark bodycoloration and subglobose pronotal disc) and P. (P.) davidpearsoni sp.nov. (by its paleappendages), but the labrum in P. (P.) sericina is much longer in both sexes and withmuch more prominent teeth. Moreover, P. (P.) sericina is immediately recognizablebecause its elytra lack the large, smooth catoptric patches (they possess only darkenedpunctate areas with lustrously shiny intervals between the deep punctures, irregularlyoccurring from basal to apical elytral areas), the pronotum possess a different surfacesculpture, the scape has only the apical and one discal seta, and the aedeagus has muchlonger apex and very different structure of the internal sac with much shorter ventral spurand with characteristic, oblong, longitudinally placed central piece with acute apex andangular base. In addition, the elytral humeral lunule of P. (P.) sericina consists oflongitudinal lateral band with a rounded or angular mesad directed posterior appendage,and besides the setose anterior and lateral areas of the metasternum and median area ofthe proepisterna, also ventral area of the prosternum possesses a few, erect setae.Etymology. The new species is named in the honour of Prof. David. L Pearson (ArizonaState University, Tempe), the well known specialist in the ecology, biodiversity, biologyand natural history of tiger beetles.Biology and distribution. The adults of P. (P.) davidpearsoni sp.nov. were taken by thesecond author in three localities in the province of Cordillera in the drier southern part ofthe large department of Santa Cruz. The type locality south of Camiri along the road tothe small town of Cuevo (20°31′S, 63°34′W), 900�950 m.a.s.l., lies about 340 km southof Santa Cruz de la Sierra, the capital of Santa Cruz Department. The second locality isabout 7 km west of the type locality along the same road. The third locality, 6.8 km southof Abapó on the Río Grande River is situated about 150 km south of Santa Cruz de laSierra. The adults of this new species always occupied small �quebradas� � small claystream cuts, some as much as 2 to 3 metres deep. Similar to most other species of the


28


nominotypical subgenus of Pentacomia, the new species is shade-loving and their larvaltunnels can be found in clay banks. Unfortunately, no larva was successfully dug out ofthe tunnels.Remarks. Specimens of this new species were partly confused with P. (P.) speculiferaand listed under that name by PEARSON, GUERRA & BRZOSKA (1999) with the citations ofthe localities in Type material above, together with the two recent Bolivian localities ofP. (P.) speculifera. On the map of the distribution of P. (P.) speculifera published by theseauthors, the southernmost marks are in fact marks for the distribution of P. (P.)davidpearsoni sp.nov.
